It indeed looks like we just need to handle the case where it runs out
of segments on one string.
But we have to handle two cases : run out of segments with the
-release number or without it.
So in both cases, I handle it differently if the last remaining
segment starts with a letter or not.

I am not 100% sure that it will work correctly in every single cases,
but the logic seems alright, there is no regression on all existing
vercmp test, and the 4 new tests you posted in an older thread now
pass fine.
